Compare 3 free self-hosted password managers: Vaultwarden (Bitwarden-compatible, ~10MB RAM), Padloc (E2E encryption), Psono (team features). Docker setup, security hardening guide. Updated 2026.
Vaultwarden is a lightweight reimplementation of the Bitwarden server in Rust with 43K+ GitHub stars. It works with all official Bitwarden browser extensions, mobile apps, and CLI tools, but uses only ~10MB of RAM instead of the 2GB+ required by the official Bitwarden self-hosted server. This makes it perfect for a Raspberry Pi, home server, or $3/month VPS. Search interest grew 83% year-over-year in 2026 as Bitwarden subscription prices increased and users seek free self-hosted alternatives.
Yes. Vaultwarden is fully compatible with all official Bitwarden clients: browser extensions (Chrome, Firefox, Safari, Edge), mobile apps (iOS, Android), desktop apps, and the CLI tool. You keep using the same Bitwarden apps — just point them to your self-hosted server.
Vaultwarden uses ~10MB RAM vs 2GB+ for the official server. It covers all personal and small team features. Use the official server only for enterprise features like SSO, SCIM, or organizational policies.
Always run Vaultwarden behind HTTPS (use a reverse proxy like Caddy or Nginx with Let's Encrypt). Enable admin panel with a secure token. Keep the Docker image updated.
Yes. Vaultwarden runs great on Raspberry Pi 3+ with just 50MB RAM. Use the Docker image: docker run -d -p 8080:80 vaultwarden/server. Pair with Caddy for automatic HTTPS.
Vaultwarden is best for individuals and small teams who already use Bitwarden apps. Padloc offers the cleanest modern UI with end-to-end encryption. Psono is best for teams needing LDAP/AD integration, API access, and audit logging.
